The invention discloses an engine respirator exhaust structure. The engine respirator exhaust structure comprises a respirator exhaust pipeline; the respirator exhaust pipeline comprises a condensation pipeline positioned between an inlet end and an outlet end of the respirator exhaust pipeline; the condensation pipeline is provided with a cooling structure and an openable discharge port; the cooling structure is configured to cool fluids flowing through the condensation pipeline; and the discharge port is used for discharging water liquefied after cooling from the respirator exhaust pipelinein an engine idling state. The condensation pipeline is arranged in front of the outlet end of the respirator exhaust pipeline, and is provided with the cooling structure and the water discharge port;part of water vapor in the respirator exhaust pipeline can be liquefied before reaching the outlet end of the respirator exhaust pipeline; and in the engine idling state, the water liquefied after cooling is discharged from the respirator exhaust pipeline, so that the water content of the outlet end of the respirator exhaust pipeline can be greatly reduced, and the icing blockage risk of the outlet end of the respirator exhaust pipeline is reduced.
Description
technical field [0001] The invention relates to the technical field of rail transportation, in particular to an air outlet structure of an engine respirator. Background technique [0002] The gas discharged from the engine respirator contains a lot of water vapor. The outlet pipe of the respirator is long and the outlet end of the respirator outlet pipe is far away from the engine outlet. In a cold environment, the outlet end of the respirator outlet pipe will freeze. The phenomenon. [0003] However, if it has been in a low temperature environment, the amount of water vapor at the outlet end of the respirator outlet pipe continues to accumulate, and the outlet end of the respirator outlet pipe will freeze and block, which will cause excessive internal pressure of the engine and cause engine damage. Contents of the invention [0004] The object of the present invention is to propose an engine respirator air outlet structure capable of reducing the water content of the out...
